Even though it's quite unlikely to happen in this particular
case, clk_get_rate can return '0' if sdd->src_clk is not set
properly. In that case we would have a clear division by '0'.
Check the return value of clk_get_rate and fail in case it
returns '0'.
This patch fixes '1397922 Division or modulo by zero' from
